Given numbers are 836,781,589,759
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,781,589,759 is 126962484.
Find LCM of 836,781,589,759 with Prime Factorization
| 11 | 836, 781, 589, 759 |
| 19 | 76, 71, 589, 69 |
| 4, 71, 31, 69 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 4 x 71 x 31 x 69 = 126962484
Therefore, the lowest common multiple of 836,781,589,759 is 126962484.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
836 x 781 x 589 x 759 = 291886750716
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
781 : 1, 11, 71, 781
589 : 1, 19, 31, 589
759 : 1, 3, 11, 23, 33, 69, 253, 759
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,781,589,759, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
781:11x 71
589:19x 31
759:3x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11x 19 = 2299
Therefore, the value for common factors is 2299.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 291886750716/(1x2299)
LCM = 291886750716/2299
LCM = 126962484
Thus, we can understand that the LCM of 836,781,589,759 is 126962484.
